Stove connection to twinwall

[markocosic]

This is the stove connection. Manual says "130 mm" flue" is required.

 

In practice it is approx 129 mm OD / 123 mm ID:

 

 

How would we go from this to "130 mm" twinwall:

Do we need something like a "120 to 130 mm increaser" and sealing material? (i.e. 130 mm twinwall is 130 mm OD for the liner)

Or is "130 mm" twinwall more like 120 mm OD for the liner?

 

I can ask supplier but language barrier for me / weekend etc.

Answer:

 

Pop the connection off the stove; chop the existing 129mm OD ring to 1cm high, weld another ring of mild steel around it; now you have >130 mm ID for going direct to 130 mm OD twinwall without adapters.

 

Weld on the inside and water/airtight.

There are adaptors for most situations available. Not sure if this is the right one but...
